Subject: Re: Which Oil Pressure Switch?
From: "user9253" <fransew@gmail.com>
I happened across this circuit stored on my hard drive. Can not remember who
the author is. It is designed to detect an AC voltage. The output of an
alternator is not perfect DC, but has an AC component. This circuit will rectify
that AC voltage and output a DC voltage, perhaps enough to enough to enable
the Honeywell LCD LM SERIES MCU Hobbs meter. Since the meter only
requires 0.8 milliamp, its enable pin must require much less than that.
Perhaps someone can suggest resistor and capacitor values.
